Subject: [PATCH V4 0/2] blk-mq/nvme: cancel request synchronously
Date: Tue, 9 Apr 2019 06:31:20 +0800 [thread overview]
Message-ID: <20190408223122.29844-1-ming.lei@redhat.com> (raw)
Hi,
This patchset introduces blk_mq_complete_request_sync() for canceling
request synchronously in error handler context, then one race between
completing request remotely and destroying contoller/queues can be fixed.
V4:
- drop return value
- don't handle fake timeout
V3:
- avoid extra cost to blk_mq_complete_request
V2:
- export via EXPORT_SYMBOL_GPL
- minor commit log change
Ming Lei (2):
blk-mq: introduce blk_mq_complete_request_sync()
nvme: cancel request synchronously
